The Nine Years' War, sometimes called Tyrone's Rebellion, took place in Ireland from 1593 to 1603. It was fought between an Irish alliance led mainly by Hugh O'Neill of Tyrone and Hugh Roe O'Donnell of Tyrconnell against English rule in Ireland, and it was the end of Gaelic order and the Ulster plantation to populate Ireland by lowlander Scots and Brits.
The Flight of the Earls took place in September 1607, when Hugh O'Neill, 2nd Earl of Tyrone, and Rory O'Donnell, 1st Earl of Tyrconnell, and about ninety followers, left Ulster in Ireland for mainland Europe. Their permanent exile was a watershed event in Irish history, symbolizing the end of the old Gaelic order.
